The view and schema integration methodologies proposed are driven purely by semantic considerations, and allow integration of objects only if that is valid from both semantic and structural view points. The authors discuss a new integration method called structural integration that has the advantage of being able to integrate objects that have structural similarities, even if they differ semantically. This is possible by using the object-oriented Dual Model which allows separate representation of structure and semantics. Structural integration has several advantages, including the identification of shared common structures that is important for physical database design and sharing of data and methods (code reusability).<<ETX>>","PeriodicalId":376969,"journal":{"name":"[1991] Proceedings.

Classes can overlap, or be equivalent or disjoint, or one class may include another class. Computing such relationships is based on the 'subsume' function, which determines whether a given class is a superclass of another class. Relationships thus identified can be used to merge classes of two or more schemas (i.e., integrating these schemas) with the help of the classification function and other schema restructuring operators.<<ETX>>","PeriodicalId":376969,"journal":{"name":"[1991] Proceedings.

These tools are used to build systems that provide information from multiple disparate systems or data sources. As many as thirty commercial frameworks exist for integrating heterogeneous database systems and numerous integrated systems are being developed for organizations with multiple information source requirements. Unfortunately, among integration framework and system developers there is little agreement on the definition of integration or on how to describe the frameworks and what they do. The authors present a definition of integration and define parameters for describing, specifying, and comparing integration frameworks and integrated systems. The parameters are based on the integration space where the dimensions define the hiding or exposing of heterogeneities in source, scheme, data model, time/context and dependencies. The authors use these dimensions in specifications to define the level of integration provided by the integration framework or integrated system.<<ETX>>","PeriodicalId":376969,"journal":{"name":"[1991] Proceedings.

The method is based on a retrieval model which formulates each retrieval action as a transition of viewpoint in information space, where the space consists of knowledge space and data space. Following good features are derived; various types of media can be treated in an integrated way by means of knowledge space representation, and easy operations are enabled by means of visual communication between users and the system. The method is especially applicable for plant information systems because there are various types of information such as plant diagrams, sensed data and experts' knowledge, and because the man-machine interface is important to enable quick response by operators. Methods of retrieval based on similarity and on relationships which are useful as decision support facilities are discussed.<<ETX>>","PeriodicalId":376969,"journal":{"name":"[1991] Proceedings.

In the program presented, the parallelism is the maximal amount permitted by the semantics of the multidatabase transaction. A refinement of this program could restrict the parallelism to the amount permitted by the systems executing the sub-transactions.<<ETX>>","PeriodicalId":376969,"journal":{"name":"[1991] Proceedings.

The autonomy and heterogeneity of these systems present a major impediment to the direct adaptation of transaction management mechanisms developed for distributed database systems. This paper addresses the problems in multidatabase recovery. Most solutions proposed to provide multidatabase recovery are either allow incorrect results or place severe restrictions on global and local transactions. To assure that multidatabase recovery preserves the consistency of a multidatabase system. The author introduces a multidatabase recoverability requirement. He also describes a recovery mechanism that takes advantage of the local recovery in the participating database systems by minimizing the replication of recovery tasks.<<ETX>>","PeriodicalId":376969,"journal":{"name":"[1991] Proceedings.

The authors describe a new approach for finding information in a large scale network of autonomous and heterogeneous databases. The system relies on an object-oriented architecture to educate users about the available space of information and help them locate information sources. The system, named FINDIT, accommodates database autonomy as well as heterogeneity. To ensure information abstraction and encapsulation the system is divided into three categories, namely, user servers, database servers, and databases. User servers are geared towards satisfying users needs while database servers are in charge of managing databases.<<ETX>>","PeriodicalId":376969,"journal":{"name":"[1991] Proceedings.
